A Novel Method for Recognition of Bioradiolocation Signal Breathing Patterns for Noncontact Screening of Sleep Apnea Syndrome

Table 1

Selection of the optimal wavelet basis for BPBS feature extraction.

Wavelet basis	Entropy estimates
	𝐸1	𝐸2	𝐸3	𝐸𝑜
DBSH13	−31,840	−70,530	−35,636	−49,188
SMLT13	−32,790	−80,104	−44,964	−56,313
CFLT5	−39,672	−71,158	−33,537	−50,866

Where 𝐸₁, 𝐸₂, and 𝐸₃ are averaged entropy estimates for the three classes of BPBS; 𝐸_𝑜 is MEC estimates.
